Your brain has more capacity than an average LLM, and a self-supervised training regime etched into it by millions of years of evolution. Its inductive bias is very well tuned for the environment. It still takes decades to build itself up to peak performance.

And at its peak? Human brain doesn't actually have an overwhelming advantage over an LLM. It's a mixed bag of advantages and disadvantages.

LLMs think fast, and can input and output data much faster than a human. But they struggle to work on the same task for a long time, and have a problem with visual inputs and object manipulation. LLMs have more knowledge in total, but humans have better meta-knowledge, which is useful for hallucination avoidance. LLMs can only learn in context efficiently, but humans learn continuously and retain what they learned. LLMs and humans are currently trading blows when it comes to inference energy efficiency - especially when you account for things like sleep or rest.

I don't think there's a "right technology" at all. There may not be a state-change upgrade that gets us x100000 on a dime and goes all the way to an AGI on every smartphone and an ASI in any datacenter worth the name. I expect there to be a lot of little +5% and +10% upgrades that add up over time.
